Abstract
L'invention concerne une composition de matière colmatante (LCM) à déshydratation rapide qui forme un bouchon soluble dans un acide. La composition LCM peut contenir un fluide porteur, un matériau particulaire soluble dans un acide, un agent d'amélioration de la viscosité et des fibres de rachis de dattier. Le fluide porteur peut être l'eau et l'agent d'amélioration de la viscosité, une microfibre cellulosique. La composition LCM peut modifier une zone à circulation perdue par formation d'un bouchon soluble dans un acide dans une fracture de ladite zone. Le bouchon soluble dans un acide peut ensuite être retiré par l'intermédiaire d'une solution acide, telle qu'une solution d'acide chlorhydrique. Des procédés de colmatage et de production d'une matière LCM à déshydratation rapide sont en outre décrits.
